ST STB5NK50Z/-1 - STD5NK50Z/-1 STP5NK50Z - STP5NK50ZFP N-CHANNEL 500V - 1.22Ω - 4.4A TO-220/FP-D/IPAK-D2/I2PAK Zener-Protected SuperMESH™MOSFET features: typical RDS(on) = 1.22 Ω, extremely high dv/dt capability, improved ESD capability, 100% avalanche rated, minimized gate charge, very low intrinsic capacitances and very good manufacturing repeatability. Applications: high current, high speed switching, ideal for off-line power supplies, adaptors and PFC, lighting.
The SuperMESH™ series MOSFETs from STMicroelectronics provide 500 V blocking voltage, low on‑resistance and high dv/dt capability for demanding power‑supply, adapter and lighting applications. The devices feature Zener‑protected gate structures, avalanche‑rated operation and minimized gate charge.
Key specifications include a continuous drain current of 4.4 A at 25 °C, a total power dissipation of 70 W in a TO‑220 package, and built‑in back‑to‑back Zener diodes for ESD protection. The series is offered in DPAK, IPAK, TO‑220 and TO‑220FP packages, with ECOPACK® lead‑free packaging for environmental compliance.
